Tannin 1 kg

Why Winemakers, Tanners and Formulators Rely on This Plant-Based Astringent

Tannin is a naturally occurring astringent compound extracted from oak bark, chestnut wood, gall nuts and other plant sources, valued across industries for its binding, antioxidant and precipitating properties. This raw material belongs to the Chemical Raw Materials section and the 1 kg pack size makes it practical for lab trials, small production batches, home winemaking projects and precisely dosed cosmetic formulations where measuring exact quantities matters.

The largest historical application remains winemaking, where the compound is used to clarify and stabilize young wines, precipitate excess protein and adjust astringency and structure. Typical dosing ranges from 5 to 15 grams per 100 liters of must, though exact amounts depend on grape variety and fermentation stage and should be tested in small trials first. The second major industry is leather tanning, where the compound reacts with animal hide proteins to produce durable, water-resistant leather with characteristic fiber structure.

In food production, tannin functions as a natural antioxidant and flavor stabilizer in beverages, tea blends and certain confectionery products. In this sector it is often paired with other food-grade additives such as Food Grade Tartaric Acid, which regulates acidity levels and further stabilizes beverages during joint storage and processing. The compound is also used in ink and textile dye manufacturing and in photographic developing solutions.

In personal care manufacturing, tannin is prized for its astringent effect, making it a common addition to toners, lotions and formulas targeting oily skin and enlarged pores. Standard working concentration in finished water phases ranges from 0.1 to 1 percent, added during water phase mixing at temperatures not exceeding 40 degrees Celsius to preserve the active compounds. When formulating emulsions, compatibility with thickening agents should be tested beforehand, since tannin can interact with certain polysaccharide structures. A commonly used thickener in such formulas is Guar Gum, which builds stable texture without compromising the astringent function of the main ingredient.

In chemical processing, tannin is occasionally combined with organic acids in flux production and metal surface cleaning applications that remove oxide layers. In such technical chains, Formic Acid 85 percent is sometimes used to intensify cleaning action and accelerate reaction with metal surfaces.

Store tannin in a dry area away from direct sunlight, in a tightly sealed container that prevents contact with air moisture, since the compound is hygroscopic and prone to clumping under humid conditions. Recommended storage temperature is between 15 and 25 degrees Celsius, away from heat sources and open flame.
